Short description Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 27-31; Anal spines: 3; Anal soft rays: 24 - 28. Body dark olive-brown. Orange spots on head. Pectoral fin yellowish, caudal and ventral fins brown, anterior part of caudal fin pale. Each side of caudal peduncle with sharp, forward-pointing erectile spine which folds down into a horizontal groove. Scales minute. Juveniles with 8 - 12 pale stipes inclining downward and backwards on body. Teeth movable, slender, tips incurved and expanded; upper jaw 5-6 denticulations, lower only 3-4.

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-Pacific: throughout the region excluding the Hawaiian, Marquesan and Easter islands. Record from Baker Island (US Minor Islands) based on a photograph (Ref. 42056). Absent from Malden and Jarvis islands (Ref. 1602).

Biology     Glossary (e.g. epibenthic)

Inhabits reef flats and lagoon and seaward reefs to a depth of over 30 m. Occurs over coral (Ref. 58534), rock, pavement, or rubble substrates. May occur singly or in small to very large, often mixed-species aggregations (Ref. 48637). Feeds on surface film of blue-green algae and diatoms (making this species a key link in the ciguatera food chain) as well as on various small invertebrates.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.01313 - 0.03326), b=3.00 (2.86 - 3.14), based on LWR estimates for species & Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.0 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Tmax = 34; K=0.87).
Vulnerability (Ref. 59153):  Low vulnerability (17 of 100) .
Price category (Ref. 80766):   Medium.
